ASSEMBLY INSTRUCTIONS

1. Remove tiller from shipping crate.

2. Screw the handle bar adjustment crank into the lower handle bar adjuster pin.

3. Fasten handle bar to tiller using the 1/2" x 3" bolt supplied.

4. Adjust clutch cable by removing all slack in lever.

5. Check reservoir according to instructions in service information on the following page.

6. Fill engine with fuel and oil according to the engine manual.

7. Free wheel hubs: Pull one free wheeling pin slightly, using the split ring. Rotate the pin
until the 1/8" diameter roll pin aligns with the slot in the mounting plate. Allow the pin
to slide through the slot. Repeat for the other wheel. Roll the tiller until each pin drops
into a hole in the hub. The hubs are now locked.

8. Uncoil the wire for the remote engine on/off switch. Route the wire along the clutch
cable to the engine and secure with the cable ties provided. Splice this wire to the kill
switch wire on the engine with the electrical splice provided.

SERVICE INFORMATION

1. Check reservoir level using sight glass on the left side of the tank. If required, add to
reservoir with tractor transmission hydraulic oil (Shell DONAX TD FLUID or comparable).
Recheck oil level after the tiller has been run and oil has been circulated through the wheel
and tine motors. Routinely check level thereafter. DO NOT OVERFILL THE TANK.

2. Change the hydraulic oil filter after the first 50 hours of use. Change it after every 200 hours
thereafter.

3. Add 1 quart of hydraulic oil to the reservoir with each oil filter change.

4. Check the tine bolts after each use and tighten as needed. Check all hydraulic fittings for
leaks and tighten if necessary.

5. Tines should be changed as often as needed for the machine to do a satisfactory and efficient
tilling job. Use Loctite 271 (red) on tine bolt threads to prevent loosening.

6. The grease zerk on the outboard end of the tine shaft flange bearing should be greased after
every 4 to 8 hours of use.

7. Grease zerks on the axle ends (to lube wheel hubs) should be greased once a week or so,
depending upon freewheel use.

IMPORTANT: The engine is normally serviced prior to shipping. However, shipping
regulations may prohibit this. Check levels and add oil and fuel as required before starting.
Service according to the engine manual before starting.

WARNING: Running the tiller without hydraulic oil will cause serious damage to the hydraulic
pump. CHECK RESERVOIR LEVEL BEFORE STARTING THE MACHINE.

KEEP ALL PERSONNEL CLEAR OF MACHINE

DURING BREAK IN TO PREVENT INJURY!!

Before using tiller, lower the depth bar to raise the tines off the ground. Tape clutch handle in
closed position and let the machine run for 30 minutes at half throttle with tines in motion.
